ATRPositionSizer

The ATR Position sizer allows the trader to size Forex and Equity positions based on how much % movement in equity is allowed within a predefined ATR range period.
Current default settings are:

The calculated trade size = N*ATR Movement = % Up/Down Movement in Equity = 1 Unit

N is an ATR multpile.
ATR time frame is defaulted to weekly and can be changed.
% Unit Risk is set to 0.5 and can be changed.

The ATR position sizer plots the recommended trade size (green) and equity line (blue).
A maximum allowed capital allotment to any given trade can also be specified in terms of %. If trade size exceeds max capital allocation, the trade size line turns red.

This type of sizing approach is useful when managing a portfolio of assets.
